Soo.. it seems at least 95% better now for no apparent reason. I just put a fresh tank of fuel in it and it seems happy. Weird considering this is my daily driver.
No misfires, and maybe only a hint of hiss at full throttle full revs.
I know i should just be glad, but i like to understand why it was screwy in the first place.
I'll just monitor it for weird behavior/

Anyway, thanks for the help
